The Konami Code, known in Japan as the Konami Command, is a cheat code that appears in many Konami video games, although the code also appears in some non-Konami games. The code was first used in the 1986 release of Gradius for the Nintendo Entertainment System but was made famous in North America in the NES version of Contra, for which it was also dubbed the "30 Lives Code". While pausing the game or during the title screen, the player could press the following sequence of buttons on the game controller: Up Up Down Down Left Right Left Right B A. The code was subsequently re-used in a large number of other games, and has found a place in popular culture as a reference to the third generation of video game consoles. It is also the only standard way to put a Palm webOS device (such as the Palm Pre or Palm Pixi) into developer mode. The original version of the cheat code was designed for the NES controller. In many popular representations of the code, Start is added at the end of the sequence. Select is also sometimes inserted at the end of the code. The exact sequence varies from game to game, and has been adapted to fit the button layouts of different video game consoles.
